Question

question 9 (1 point)
calculate the density of oxygen at stp using the volume from problem 7 (7.329 l) and the mass from problem 8 (10.46 g)
mass _1_ g
d = ----------- = ----------- = _2_ g/l
volume _3_ l
a. 1.000 b. 273.15 c. 7.329 d. 22.414 e. 0.08205 l atm/mol k
f. 10.46 g. 1.428 h. 32.00 i. 4.000 j. 6.000 k. 2.000
l. 1.000 m. 298.15

Explanation:

Step1: Identify mass and volume values

The formula for density \(D=\frac{\text{mass}}{\text{volume}}\). Given mass \( = 10.46\space g\) (from problem 8) and volume \(=7.329\space L\) (from problem 7).

Step2: Calculate density

Substitute the values into the formula: \(D=\frac{10.46}{7.329}\).
Using a calculator, \(\frac{10.46}{7.329}\approx1.428\space g/L\).

Answer:

1. F. \(10.46\)
2. G. \(1.428\)
3. C. \(7.329\)
